Do you think he was being truthful with you or do you think that he was not willing to tell you what he really thought? He had to be lying to you, no?
To give him credit at least he was fairly upfront about it - he said basically 'I have no way of knowing this, but I believe it to be true.' At least he didn't try to say that he knew
that he was clean. I'd rather get a fairly straight answer like that then when I asked an ex-pro who rode on Armstrong's team and just got some textbook dancing around the question, "thorny subject" etc.
Was Liggett lying? My view is that he's a bit like one of those TV evangelists that just happens to be raking in cash from people's belief. Who knows whether he actually believes himself and the money-grabbing opportunity grew out of the belief, or whether his beliefs were concocted in order to create the money-grabbing opportunity.
(The other possibility for his lying would be that he knows
for a fact that Armstrong is
doping and is complicit. I do wonder about this and about whether it is really possible to hide systematic team doping when you're staying in the same hotels as journalists. It would certainly be a lot easier if the journalists knew full well what was going on but had been persuaded that it wasn't anything of interest.)
